A registered behavior technician (RBT) works under the supervision of a licensed therapy professional. Your RBT won't develop an autism treatment plan, but this person will work closely with the person you love during applied behavior analysis (ABA) therapy sessions. An RBT arrives to work with a formal treatment plan that includes a trigger, a current response, and an ideal replacement. In each session, an RBT offers that trigger and then gives rewards for the replacement act. Sessions are fast paced, and they're often quite fun. RBTs are generous with praise, and they develop tight connections with their clients. Seeing maladaptive responses fade is their ultimate reward.
